Looking near the origin at plots of y = x^n for ever tinier n, a student wonders why y
= x^0 does not equal zero. By emphasizing two different limits, Doctor Ali gets the
student back into line -- specifically, y = 1.

Hope you'll help a graduate student trying to understand an example in an
economics textbook. It involves food production and the equation is: Q =
100(K[superscript.8]L[superscript.2]). K involves machines and L involves
labor. The diagram shows Q(output) as 13,800, L as 760, K as 90. I have
been unable to figure out how to make the equation reveal those numbers.
